THE ROTATIONAL-CONFORMATIONAL DISTRIBUTION OF 2,2'-BITHIENYL IN LIQUID-CRYSTALS

We have investigated the distribution of conformations and orientation s for a simple internal rotor molecule, 2,2'-bithienyl dissolved in li quid crystal solvents. by re-analysing published proton dipolar coupli ng data with the maximum entropy internal order method (MEIO). We show that detailed, model independent, conformational information can be o btained when data of sufficiently high quality are available. We also propose a novel and convenient representation method for the orientati onal-conformational coupling.
